Being an Industrial Engineer (IE), I was given amazing opportunities, space and flexibility in my research to be creative, to be an entrepreneur, and to make changes in people's lives. My core research is system modeling and decision making for complex system/operation design, monitoring, and evaluation. By analyzing the dynamics of system behaviors and dependencies among individual agents within the systems, we may develop a policy (evidence-based practice) to manage such system and mitigate its risks. Applications of this concept include manufacturing, warehouses, supply chains, water treatment system for mission to Mars, riot prediction, humanitarian aids, healthcare engineering, as well as addressing global challenges in developing countries.
